Solve the following

I want to find the spectral decomposition of A, Which is find unitary U and a diagonal D so they can form A = UDU* Let A 6 2 =These are short scenarios for decision making. 1) For a test of hypothesis, assume the following information is given. Ho : H = 10 Ha : H > 10 Alpha = 0.10 n = 100 test statistic is t = 1.934 p-value = 0.027 Should we reject Ho ? 2) For a test of hypothesis, assume the following information is given. Ho : p = 0.5 Ha : P
